Numbers 22:10

And the children of Israel set forward, and pitched in the plains of Moab on this side Jordan by Jericho.

And Balak the son of Zippor saw all that Israel had done to the Amorites.

And Moab was sore afraid of the people, because they were many: and Moab was distressed because of the children of Israel.

And Moab said unto the elders of Midian, Now shall this company lick up all that are round about us, as the ox licketh up the grass of the field. And Balak the son of Zippor was king of the Moabites at that time.
